True story from visiting my sister in Barcelona

This is a true story and I’m using a throwaway account as I wouldn’t want any of my friends to ever see this but it’s something I need to get off my chest.

So long story short my (M23) sister (F21) was studying abroad in Barcelona last summer. My family decided to take a trip to Spain while she was there and link up with her the week she finished. We’ve always been super close and been extremely open sex and our experiences compared to the average siblings. We also over the year have been flirty when drunk but nothing ever came of it as I think we both realized how wrong it would be.

When we got to Barcelona to meet up with my sister my parents got two rooms, one for my sister and I and one for them on a separate floor. I was excited to see my sister as I had been with my parents the last three weeks and was looking forward to going out with her and her study abroad friends to experience the night life in Barcelona. The first morning we got there we checked into the hotel then headed to the beach with our parents. It just so happened to be a nude beach which obviously none of us took part in but after seeing families there where the moms and sister were naked I wished I could see my sister topless. My sister is definitely “hot” and I’ve always gotten shit for it from friends. She’s blond and 5’7 with an athletic build with large breast (guessing Cs) and a big butt.
